GAVELCARRIER FOR GRAIN-HARVESTERS.

SPECIFICATION forming part of Letters Patent No. 439,710, dated November 4, 1890.

Application iilecl July "7, 1890. Serial No. 357,930. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM G. WHITING, of Wallington, in the county of Wayne and State of New York, have invented a new and useful Improvement in GavelCarriers for Grain-I-Iarvesters, which improvementis fully set forth in the following speciiication and shown in the accompanying drawings.

My invention relates to self-binding grainharvesters; and it consistsin means and mechanism for carrying the gavel from the reaperplatforin to a point at the side. of the reaper, where it is presented to the binding mechanism' 'o in consists, also, in various other devices and parts constructed and arranged substantially as shown, the invention beinghereinafter f ully described, and more particularly pointed out in the claims.

Referring to the drawings, Figure l is a plan of my invention with parts broken away and other parts shown in two positions by full and dotted lines; Fig. 2, a side elevation seen as indicated by arrow in Fig. l, the platform and base-board being sectioned, as on the dotted line zz; Fig. 3, a view of the parts seen as indicated by arrowl y in Fig. l, the platform b eing sectioned, as on the dotted line x in said gure,parts being omitted. Fig. 4, viewed the same as Fig. 3, shows other parts of the device; Fig. 5, the clutch mechanism of the vdriving-shaft. Fig. (5, drawn to a larger scale,

shows the mechanism for turning the carrier, the wheel being in part sectioned. Fig. 7 shows the means for lifting the wind-guard. Fig. 8 shows the mutilated gears. Fig. 9, viewed the same as Fig. 3, shows the means for operating the outer compressor; and Fig. l0 a sido elevation of the device for throwing the machine out of gear.

Referring to the parts shown in the draw- Aings,A is the platform of a reaper of common construction, curved to have the gavels cleared therefrom by an ordinary reel or sweep rake (not shown) in the usual manner.

B is a secondary platform on a plane a little below the platform A, consisting of a swinging carrier for the gavel.

C is the base-board of the device. The carrier B is arranged to turn horizontally upon a vertical pivot a to the position shown in dotted lines in Fig. l, the grain being delivered upon said carrier from the platform A by means of the rake beforethe carrier starts.

The binding mechanism, which forms no part of my invention, is located at the right of Fig. l, D being the needle.

The moving parts ofthe device are oper- The shaft o turns loosely within the pinion,

and the latter turns with the shaft only when thrown against a pin frigid with the shaft. (Shown in Fig. 5.)

g is a horizontal shaft held in the frame E, carrying a gear h, engaged by the pinion c to drive said shaft. This shaft is also provided with a mutilated gear t' and a bevel-gear 7o.

n is a shaft in the frame at right angles with g,in the same horizontal plane, provided with a bevel-gear l, engaged by the gear 7c, by which said shaft fn is turned.

o is a gear upon the shaft n, by means of which the binding mechanism maybe driven.

p is a horizontal shaft held in the frame provided with a rigid pinion r, which is turned at intervals by the mutilated gear t'. This gear has as many teeth as there are teeth on the pinion, and the shaft p is turned and then rests while the blank part of the gear is passing the pinion, and then is turned again. This intermittent motion of the shaft p causes the carrier B to swing out, rest, and return, and then it rests, waiting the collection of another gavel frombeing thrown out ofgear.

s is a crank on the shaft p, connected by means of a pitnian t to a horizontal reciprocating bar u, fitted to slide longitudinally in the frame. The pivot-shaft ct of the carrier B is provided with a grooved wheel@ beneath the carrier, said wheel being tangent to the bar a, and a cable or cord w, making a turn around the wheelin the groove, has its ends crossed and secured to the bar at points respectively near its ends. It will be seen from this description that a single revolution 'of the crank s will cause the carrier to swing IOO away from the platform A and return. The extent of the horizontal motion of the bar 'a is made to equal about one-fourth of the circumference of the grooved wheel, so as to turn the carrier through about ninety degrees ot arc.

a is a retainer for the gavel on the carrier B, and b is a discharger for the bound bundle. The retainer is pivoted to the shaft a, so as to swing in a vertical plane, and it serves to prevent the wind from disturbing the loose grain on the carrier. The discharger for the bundle is operated by a crank d', rigid with the shaft n. A tortuous camlever e', held to turn in a vert-ical plane upon a piu j, rigid with the frame, is acted upon by the crank d', so as to give the bundle-discharger an outward thrust at the proper time, as indicated by dotted lines in Fig. 3. As the crank encounters the lever, it pushes the latter rapidly outward until the point 7L is passed, which gives the discharger its extreme outward motion. The lever is then quickly returned to its normal position by a spring y1I', the crook in the lever causing it to be out of the way of the crank during the remainder of its revolution. A rigid rest k is provided for the discharger, to hold the latter up out of the way of the carrier as the latter swings under it.

The lever e while it acts to discharge the bundle at the same time lifts the retainer ct to allow lthe bundle to pass olif the carrier. This it does by means of a projecting pin Z', bearing against the retainer, as indicated in Fig. 3, when the carrier brings the retainer over said pin.

n Ia are compressors for the gavel, held to turn on pins o in t-he carrier. Springs p', wound upon the respective pins and bearing against the compressors, tend to keep thelatter thrown apart, as shown in Fig. 2. Beneath the carrier the compressors are provided with rollers t, to follow curved tracks r and s,by means of which at the proper time the compressors are thrown toward each other, as shown in Fig. L This is when the gavel is about to be bound.

u is a trip for the outercompressorn. At its outer end the trip rests upon the bottom board C, and its inner end is held by a vertical lever t", pivoted to the frame E, Figs. and ti. At the upper end this lever is conveniently near the hub of the crank d', which is provided with a projection w to operate the lever. The outer end of the trip u is contiguous with the extreme end of the track o" and forms a continuation oi said track. When the carrier swings out to its extreme position and stops, the roller ot the outer compressors rests against the trip, as shown in Fig. i). Now, as the trip is movedoutward by the action of the part yzuan d the lever fu', it carries the compressor to the right-hand position, (shown in dottedlines in said ligure) serving to further compress the gavel as it is being bound; but at this juncture the upeser/io turned end of the trip passes beyond the roller and frees the compressor, which is instantlythrown out to the left-hand horizontal position (shown in dott-ed lines) by the action of its spring p. This is to permit the bound bundle to be 'pushcd off the carrier by the discharger l1. When the carrier starts back to its normal position, the compressor rides upward along the curved rod or bow a2,Figs. l and 4. This brings it nearly to a vertical position or sufficiently erect to cause the roller to be caught by the branch b2 of the track r', and so as the carrier returns to place be brought, on account of the form of the track, to the position shown in Fig. 2. When the parts are all in their normal positions and at rest, the pinion cis disengaged from the driving-pin 1", the crank-arm c ot' the shifting mechanism occupying the position shown in dotted lines in Figs. 1, 3, and 10. The rake (not shown) that carries the grain from the platform onto the carrier B encounters the arm c and turns it to the position shown in full lines in said Figs. 1, 3, and 10. This throws the pinion c over against the driv ing-pin f, which catches in the groove c2, Fig. 5, and sets the parts in motion. Vhen the parts are at rest in their normal position, the middle tooth of the mutilated gear-'z' is engaged with the pinion r, so that when the pinion c is thrown into gear, as just above stated, the pinion r is immediately turned through a half-revolution by the gear. This moves the carrier out to the position shown in dotted lines in Fig. l. At this juncture the blank part of the gear i reaches the pinion r, and the motion of the carrier ceases during the passage ot said blank part by the pinion. It is during this dwell of the carrier that the above-described actions of the trip u and the discharger b take place and the binding of the bundle is accomplished. When the gear t' again presents its teeth to the pinion r, (see Fig. 8,) the latter is turned through another half-revolution, or until the carrier is brought to its normal position of rest next the platform. As the carrier is approaching this position of rest, the pinion c is automatically thrown out of gear or awayfrom the pin f by the following means: diFigs. l and l0, is arod held to slide horizontally in a standard e2, rigid with the carrier, to bear against the crank-arm c. The rod is provided with a spring fitto urge it forward against the crank-arm, and further formed with an extended part g2 to move along a guide h2, also rigid with the carrier. This rod is so placed that when the carrier is returned to place it encounters the crank-arm and throws it over to the position shown in dotted lines, in which the pinion cis thrown back from the driving-pin j". All the parts will then remain at rest and be inoperative until the rake, as above described, encounters the crank-arm and again throws the pinion into gear. When the rake moves the crankarm to the position shown in full lines, it does so against the action of the spring f2, but the IOC yielding of the spring admits of this, while the action of the spring unopposed is capable of throwing the crank-arm over, as above described, to disengage the pinion c.

The crank-arm is secured toarod 2, Figs. l, 2, and 4, beneath the platform. A hook k2, hinged to the under side of the platform, reaches out under the carrier B to engage a boss Z2 rigid with the carrier. beneath the hook and provided with an arm 'n2 to bear against the hook. Now, when the rod d2 turns the crank-arm, as above described, it raises the hook so as to engage the boss and so hold the carrier steady with reference to the platform while the carrier is at its normal position. When the rake turns the crank-arm, it allows the hook to fall away from the boss and thus release the carrier.

The crank s, Fig.2,is formed with a slot s2, in which to receive the pin o2, so the latter may be adj usted to give to the carrier a greater or less extent of swing. This is for the purpose of presenting the gavel to the binder, so the band may be put thereon nearer to or farther from the heads, as may be desired. VVhat I claim as my invention is l. An attachment for a self-binding har- Vester, consisting of a horizontallymoving carrier for the gavel, a. wheel rigid with the carrier, a reciprocating rod to turn the wheel, and means for operating said reciprocating rod,in combination with a compressor for the gavel held by the carrier, and a discharger for the bundle held on the frame of the machine, substantially as described.
